Death notice about king in revolution (5)
I believe the answer is:
orbit
'revolution' is the definition.
(orbit is a kind of revolution)
'death notice about king' is the wordplay.
'death notice' becomes 'obit' (I've seen this before).
'about' is an insertion indicator.
'king' becomes 'r' (r is abbreviation for rex).
'obit' enclosing 'r' is 'ORBIT'.
'in' is the link.
(Other definitions for orbit that I've seen before include "Path of a planet or satellite" , "Satellite's path" , "Track of satellite" , "Circle - influence" , "Path of one celestial body around another" .)
